When an item is renamed in an anvil then put in a chest. Then the world is upgraded to the latest snapshot. When opening the chest to see the item, it's name changes to
{"text":"name of item"}

This is still a problem, but now (of maybe it always was like this) it's happening in the creative toolbar, containers, player inventory and tame inventory.
Enchantments are lost, and custom names become {"text":"name of item"}
This relates to another issue I created.
